I'm guessing an indexscan, and that the error was caused by reading a broken item pointer from the index. (1342198864 = hex 50005450, which sure looks like the upper 5 shouldn't be there ... how big is the table, anyway?) > However, I cannot repeat the error now. Is this a bug in postgres > somewhere. If the broken item pointer were indeed in the index, I'd expect it to be 100% repeatable. I'm wondering about flaky memory or some such.
